Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski shoe having an outer shell composed of three pieces and having an excellent function especially for racing.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, there has been known a two-piece type ski boot having an inner boot 4 inside an outer shell composed of a lower shell 1 and an upper shell 2. . As two-piece ski boots, there are mainly two types shown in FIGS.

In the ski boot shown in FIG. 1, both side portions 1a of the lower shell 1 are raised to the upper side, and the ski shoe has a structure close to one piece. As described above, the ski shoe close to one piece has high rigidity on both side portions and a high response at the time of forward leaning and is excellent in operability, but on the other hand, it is inferior in fitability.
It is also inconvenient to put in and take out the feet.

In the ski boot shown in FIG. 2, the rising of both side portions 1b of the lower shell is stopped up to near the ankle, and the calf is fastened by the upper shell. In such a two-piece ski shoe, since the ankle and the calf are fastened by the lower shell and the upper shell which are separate bodies, the fitting property is excellent and the foot can be easily put in and taken out. However, on the other hand, the rigidity is low and the response when leaning forward is weak due to the small rise on both sides. That is, the operability is poor.

It is considered that the most important element required for today's racing boots is that both sides of the foot have high rigidity and excellent operability. This is the reason why many of today's top athletes use boots with high rigidity as shown in FIG. 1 even if the fit is sacrificed to some extent. Therefore, if it is possible to provide ski shoes having a higher fitting feeling while ensuring high operability, it should be possible to achieve superior results in races. However, as described above, in the conventional two-piece ski boot, the operability and fit of the ski boot cannot be compatible with each other.

[0006]

SUMMARY OF THE INVENTION Therefore, the technical problem to be solved by the present invention is to provide a ski shoe which can satisfy both operability and fit.

[0007]

SUMMARY OF THE INVENTION The present invention was devised to effectively solve the above-mentioned problems, and the rise of both side parts of the lower shell of a ski shoe is about the height of the ankle part. The inner cuff which has relatively high rigidity is extended to cover the side parts to increase the rigidity of both side parts, and the inner cuff itself is fastened. Rather than that, an outer cuff that covers the inner cuff from the outside is provided with relatively low rigidity, and by fastening this outer cuff with buckles, high rigidity on both sides and improved fit from the ankle to the calf are realized. It was done.

The outer shell of the ski shoe of the present invention is a lower shell,
It is composed of three members, an inner cuff and an outer cuff. The lower shell mainly covers the lower part of the ankle, and the inner cuff is fixed to the lower shell and mainly covers the upper part of the ankle. Further, the outer cuff is fastened with a buckle so as to wrap the inner cuff from the outside, and is fixed to both the lower shell and the inner cuff.
That is, the lower shell, the inner cuff, and the outer cuff are integrally fixed by using a fixing means that fixes these three members at one place. Therefore, the ski boots are individually 3
It is composed of members, but their integrity is sufficiently high. It is preferable to use a pin member or the like as the fixing means, and it is also preferable to use about two pins.

In the lower shell, the rising of the portions corresponding to both sides of the foot is stopped at about the height of the ankle, so that the feet can be easily put in and taken out.

The inner cuff has at least a side wall portion which covers the upper side of the ankle portion on both sides of the foot, and a front wall which supports the shin. The side wall portion is provided to compensate for a defect caused by the lower shell in which a portion corresponding to both sides of the foot has a small rise, that is, a decrease in rigidity on both sides. Further, the front wall is provided to enhance the response when leaning forward and improve the operability of the ski. From this point of view, the inner cuff is preferably made of a material having relatively high rigidity.

The outer cuff has at least two sets of upper and lower buckles, the upper buckle fastens the calf portion, and the lower buckle fastens the ankle portion. That is, the outer cuff is mainly used for fastening, and from this point of view, the outer cuff is preferably made of a material having lower rigidity than the inner cuff.

In the ski shoe of the present invention, even if a highly rigid inner cuff is used, the inner cuff itself is in a free state (that is, it is not fastened with a buckle like the outer cuff). A certain degree of deformation is possible according to the relative strength between the fastening of the ankle portion and the fastening of the calf portion by the outer cuff. That is, the inner cuff has an inner diameter at the ankle portion and an inner diameter at the calf portion,
It is possible to deform by changing relative to each other.
As described above, by providing the buckle to the outer cuff of low rigidity arranged outside the inner cuff of high rigidity and fastening it,
It is possible to achieve both high rigidity and a good fit.

Further, one of the hook portion and the buckle body constituting each buckle is fixed to the front wall of the outer cuff and the other is fixed to the side wall of the outer cuff, but the upper buckle for fastening the calf portion is fixed. Hook part (or buckle body)
And the hook part of the lower buckle (or the buckle body) that fastens the ankle part, the front wall of the outer cuff (or,
It is preferable that a notch portion extending from the side edge of the side wall) is provided. By providing such a notch, the independence of the upper buckle involved in the fastening of the calf and the lower buckle involved in the fastening of the ankle (that is, the independence of the fastening of the calf and the fastening of the ankle) ) Is increased, and it becomes possible to fasten the fitting flexibly corresponding to the shape from the ankle part to the calf part for each user, and the fitting property is improved.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a ski shoe of the present invention will be described in detail below with reference to FIGS.

In the ski shoe of the present invention, the outer shell is a lower shell,
It is composed of three pieces, an inner cuff and an outer cuff, and inner boots are arranged in this outer shell. 3 shows only the lower shell 10, FIG. 4 shows a state in which the inner cuff 20 is attached to the lower shell 10, and FIG. 5 shows a state in which the outer cuff 30 is further attached. The inner boot 40 is shown only in FIG. 5, and is omitted in FIGS. 3 and 4.
Further, FIG. 6 shows a developed view in which the inner cuff 20 and the outer cuff 30 are overlapped with each other. The ski boot shown is for the right foot, and the one for the left foot is a mirror image of this.

The lower shell 10 shown in FIG. 3 mainly covers the lower part than the ankle. As can be seen from the figure, the inner crotch side portion 11 of the lower shell 10 has a small rise, and is close to the ski boot shown in FIG. The rise of the outer crotch side portion of the lower shell 10 is also small. As described above, in the ski shoe of the present invention, since the rising of both side portions of the lower shell is made small, it is easy to put the foot in and out.

As shown in FIG. 4, the inner cuff 20 is attached to the lower shell 10. The inner cuff 20 is connected to the lower shell 10 at side hinge portions 60 such as cant adjusters on both sides, and is fixed to the lower shell 10 by a fixing means such as a pin 50 on the back side of the ski boot, and is mainly fixed above the ankle. cover. As will be described later, the pin 50 integrally fixes not only the inner cuff 20 but also the outer cuff 30 to the lower shell 10.

On both sides of the lower shell 10,
Although the rigidity is reduced by the amount that the rising is small, the rigidity of both side parts is increased by attaching the inner cuff 20 to the lower shell. That is, the inner cuff 20 includes side wall portions 21a and 21b that cover both side portions of the foot. Further, front walls 23a and 23b are connected to the side wall portions 21a and 21b, respectively (see FIG. 6). Front wall 23
a and 23b are overlapped with each other and anterior part (shin) of foot
It is supported so that it covers the body and enhances the response when leaning forward. Support strength by omitting one of the front walls or changing the overlap area as required.
(That is, the degree of response when leaning forward) can be adjusted.

As can be seen from FIG. 6, the side walls 21a, 21b of the inner cuff have a narrower width, and the width of the side walls 21a, 21b decreases from the upper side to the lower side.
However, the rigidity of both side portions can be increased or decreased depending on the size of the cut portion. That is, if the notch is made smaller, the rigidity is increased, but on the other hand, the flexibility of the inner cuff is decreased and the fit feeling is decreased. On the contrary, if the notch is enlarged, the rigidity decreases,
The flexibility of the inner cuff is increased and the fit is improved. In other words, it is possible to adjust the balance between rigidity and fit by changing the size of the cut portion.

As shown in FIG. 5, the outer cuff 30 is attached so as to cover the inner cuff 20. Outer cuff 30, pin 50
It is attached to the inner cuff 20 and the lower shell 10 by using a fixing means such as. Two pins 50 are used on the back side of the ski boot, but each pin 50 has a lower shell, an inner cuff,
And the three members of the outer cuff are fixed at one place.
Therefore, the integrity of the three members forming the outer shell of the ski boot is enhanced. In addition, in FIG. 4, in order to make the structure of the ski shoe easy to understand, an inner cuff is attached to the lower shell 10.
Although only 20 is shown attached, in practice the inner and outer cuffs are integrally attached to the lower shell using pins 50. That is, only the inner cuff is not attached to the lower shell.

The outer cuff 30 is used to fasten the inner cuff 20 from the outside and has two sets of upper and lower buckles. As shown in FIG. 6, each buckle has a hook portion 31,
It is composed of 32 and buckle bodies 131 and 132. The hook portions 31 and 32 of each buckle are fixed to the front wall 35 of the outer cuff 30, and the buckle bodies 131 and 132 are the side walls 36 of the outer cuff 30.
It is fixed to. A notch 70 extending substantially horizontally from the side edge of the front wall is formed between the hook portions 31 and 32 which are fixed to the front wall 35 so as to be vertically aligned. The notch portion 70 divides the hook portion 31 involved in fastening the calf portion and the hook portion 32 involved in fastening the ankle portion into upper and lower parts. As a result, the independence between the fastening of the calf portion and the fastening of the ankle portion is enhanced, and the fastening that flexibly corresponds to the shape of each user from the ankle portion to the calf portion can be performed, and the fitting property is improved. From the same point of view, a notch 71 is also formed between the buckle bodies 131 and 132 which are fixed to the side wall 36 by arranging them two by one.

Although the arrangement of the hook portion and the buckle body may be reversed (that is, the hook portion may be fixed to the side wall and the buckle body may be fixed to the front wall), but for the buckling operation of the buckle. It is convenient to fix the buckle body to the side wall.

In the example shown in FIG. 6, the notches 22a and 22b formed on the side walls 21a and 21b of the inner cuff 20 are large,
A recess 28 is formed in the back surface 26 of the inner cuff. In this case, the inner cuff 20 has a smaller rise in the back surface portion 26, but the back surface portion 37 of the outer cuff 30 covers the recess 28 of the inner cuff 30.
Since a large rise has been made, a sufficient amount of backward tilting strength can be secured. By providing such a concave portion 28 on the back surface portion 26 of the inner cuff, the side wall portions 21a and 21b can follow the shape change from the ankle portion to the calf portion for each user, and the fit feeling is improved. Of course, it is also possible to omit the concave portion 28 formed on the back side of the inner cuff and secure the rising of the back side of the inner cuff. In that case, the rigidity and the rearward tilting strength on both sides are very high, which is very preferable for racing.

In the ski shoe of the present invention, it is preferable that the inner cuff and the outer cuff have different hardness.
That is, as described above, the inner cuff is intended to increase the rigidity of both side portions, and therefore it is preferable that the inner cuff is stiffer than the outer cuff. On the contrary, the outer cuff has a different foot shape for each user (shape from the ankle to the calf)
Since the purpose is to realize a flexible fastening that flexibly corresponds to, it is preferable that the inner cuff has higher flexibility. The ski boot according to the present invention has both operability and fit feeling of the ski boot, but the higher the rigidity of the inner cuff, the higher the specific gravity with respect to the operability of the ski boot. Therefore, it is preferable to increase the rigidity of the inner cuff as it becomes more advanced, such as when it is used for racing.

Even if a highly rigid inner cuff is used, the inner cuff itself is in a free state (that is, it is not fastened with a buckle like the outer cuff). It is possible to deform to some extent according to the relative strength between the fastening of and the calf portion. That is, the inner cuff can be deformed by changing the inner diameter of the ankle portion and the inner diameter of the calf portion relative to each other.

Next, a modified example of the outer cuff will be described with reference to FIG. That is, in the example of FIG. 7, the lower shell
The 10 and the inner cuff 20 are the same as those described above, but the shape of the outer cuff is different. The buckle is not shown in FIG. 7.

In this modification, the outer cuff 30 'extends downward to the side hinge portion 60 so that the side wall portion 38 on the inner crotch side covers the entire inner side wall portion 21a of the inner cuff side. Such a structure is a design that emphasizes the side rigidity on the inner crotch side, and the degree of freedom in fastening is sacrificed to some extent. In this sense, this modified example is considered suitable for racing. Further, as still another modified example, a configuration in which only the outer crotch side wall portion of the outer cuff extends downward to the side hinge portion 60, or both side wall portions of the outer cuff are lowered downward to the side hinge portion 60. It is also possible to extend it. All of them emphasize high rigidity.
